1) line SI bushmaster: cycles great and AT works. Has what looks like a bottom line setup. Take it home for 100. Edit: this is one of the newer ones and has an adjustable bolt to mess with the velocity.

2)pmi trracer: nice loud little pump! Works perfectly. Comes with parts kit (enough stuff to replace the internals all over). Will not come with the 12g changer. Take it home for SOLD
